“说谎”作为一种概念和行为现象,在人类社会中普遍存在,这一现象在道德范围内是不被允许的,在一般社会生活中也不被提倡,它频繁的出现在我们与他人的社会互动和社会交往中,对个体和社会有着深刻的影响。为消除或减轻“说谎”所造成的负面影响,测谎技术应运而生。目前,测谎技术已被许多国家信任并被广泛应用于刑侦,民事审判等多个领域,与此同时,如何对测谎过程中的各种参数合理取值作为影响测谎结果的关键环节越来越成为被关注的焦点。针对此问题,本文提出利用遗传算法,通过人机交互的方式求解测谎参数的最优值,即对遗传算法灵活应用,进一步,通过实验和得出,将遗传算法应用于测谎参数的确定具有更大的发展潜力和应用价值。 “Lying ” as a phenomenon and phenomenon of behavior, is ubiquitous in human society. This phenomenon is not allowed in the moral context and is not advocated in ordinary social life. It frequently appears in our relations with Other people’s social interaction and social interaction have a profound impact on individuals and society. In order to eliminate or alleviate the negative effects of “lying ”, polygraph technology came into being. At present, polygraph technology has been trusted by many countries and widely used in many fields such as criminal investigation and civil trial. At the same time, how to reasonably value various parameters in the process of polygamy as the key link of polygraph results More and more to become the focus of attention. In order to solve this problem, this paper proposes the use of genetic algorithm to solve the optimal value of polygraph parameters by means of human-computer interaction, that is, the flexible application of genetic algorithm, and further, through experiments and conclusions, the genetic algorithm is applied to the determination of polygraph parameters Has greater potential for development and application value.
